That's better, but I don't see the part with which  I initialized.
brains hgs 49 %> cat !$
cat StringIOtest.rb
#!/usr/local/bin/ruby

require 'stringio'

string = "a string."
stream = StringIO.new(string)

stream << ' More text'

stream.rewind
p stream.inspect
p stream.to_s
p stream.string
p stream.string.class
brains hgs 50 %> !$
StringIOtest.rb
"#<StringIO:0xf11d8>"
"#<StringIO:0xf11d8>"
" More text"
String
brains hgs 51 %>

Why not "a string. More text"?
